What is the answer to the question 1/2 • c for c = 4 2/5 ?

42/10

Step-by-step explanation:Since the value for c is known, we substitute it into the equation. Therefore, 1/2 * 42/5 = 42/10

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
